Connecticut-based Bridgewater is the world's largest hedge fund
Chris Tarui filed a complaint earlier this year with a Connecticut agency
alleging the harassment and describing Bridgewater as a "cauldron of fear and intimidation" that kept him silent
withdrew his claim earlier this week and did not receive any financial compensation from the firm
Bridgewater also agreed to withdraw Tarui's employment restrictions
Bridgewater employees are bound to noncompete agreements
The supervisor who is alleged to have harassed Tarui is still employed at the hedge fund
Still, the case has drawn scrutiny to Bridgewater's unique culture, which Dalio describes as radical transparency
employee conversations can be recorded and viewed by other employees
Bridgewater requires workers to agree to settle claims in private arbitration
The public agency filing in Connecticut
Reached by telephone, Tarui declined to comment. His LinkedIn page says that he started as a director at private-equity firm KKR this month
2016By David A.Grogan/CNBC/Getty Images.Save this storySaveSave this storySaveIt was May of 2014
and Christopher Tarui and his supervisor were sitting together on a hotel-room couch in Denver
the world’s largest hedge fund run by one of the world’s most famed finance billionaires
were on a business trip when Tarui claims his supervisor put his hand on the small of his back
He alleges that the supervisor continued to pursue him for about a year
claiming his supervisor told him he had an “itch to scratch” and asking if he would agree to a “sexual experience” with him
who was put on paid leave two days before he filed his complaint
said he was initially hesitant to report the incidents because he worried the firm’s tendency to videotape high-stakes meetings would make his allegations public within the firm
and subsequently circulated among management
It is not uncommon for the $154 billion firm to record meetings and later show them to employees as a sort of teaching tool
New employees were treated to a recording that reportedly illustrated Bridgewater’s culture—an exchange between Dalio
and a female manager who ended up in tears on the tape
but the firm reportedly still takes surveillance so seriously that some employees have to lock up their personal cell phones every morning
a “cauldron of fear and intimidation,” as Tarui called it in his complaint
allegedly held an off-site retreat in 2012 at which employees got drunk and went skinny-dipping
according to several former employees who spoke to the Times
After several people in attendance complained
one employee responsible for organizing the event was fired
Tarui and Bridgewater both asked the Connecticut commission to withdraw the complaint
The newspaper noted that Bridgewater employees are required to settle disputes in arbitration

SAN FRANCISCO — Participation in a therapeutic mother-baby program resulted in significant symptom reduction of perinatal psychiatric conditions, Nicole Tarui, MD, told Healio at the American Psychiatric Association Annual Meeting.
Results, which were reviewed quarterly and assessed by percent change from admission to discharge, showed a mean 60% decrease in EPDS scores following treatment.
“Clinically speaking, that is a huge number,” noted Tarui, a reproductive psychiatrist and medical director of the Maternal Outreach Mood Services Program at El Camino Health in California. “What that means is, mom is able to return to baseline to take care of herself, take care of her baby and also take care of her family.”

Glycogen storage disease V (GSDV, McArdle disease) and GSDVII (Tarui disease) are the most common of the rare disorders of glycogen metabolism. Both are associated with low lactate levels on exercise. Our aim was to find out whether lactate response associated with exercise testing could distinguish between these disorders.
Two siblings with Tarui disease, two patients with McArdle disease and eight healthy controls were tested on spiroergometric exercise tests with follow-up of venous lactate and ammonia.
A late increase of lactate about three times the basal level was seen 10–30 min after exercise in patients with Tarui disease being higher than in McArdle disease and lower than in the controls. Ammonia was increased in Tarui disease.
Our results suggest that follow-up of lactate associated with exercise testing can be utilized in diagnostics to distinguish between different GSD diseases.

Introduction: Glycogen storage disease V (GSDV
McArdle disease) and GSDVII (Tarui disease) are the most common of the rare disorders of glycogen metabolism
Both are associated with low lactate levels on exercise
Our aim was to find out whether lactate response associated with exercise testing could distinguish between these disorders
two patients with McArdle disease and eight healthy controls were tested on spiroergometric exercise tests with follow-up of venous lactate and ammonia
Results: A late increase of lactate about three times the basal level was seen 10–30 min after exercise in patients with Tarui disease being higher than in McArdle disease and lower than in the controls
Discussion: Our results suggest that follow-up of lactate associated with exercise testing can be utilized in diagnostics to distinguish between different GSD diseases
Tarui disease or glycogen storage disease VII (GSDVII) and McArdle disease (GSDV) are characterized by exercise intolerance, cramps and myoglobinuria or rhabdomyolysis, and very low lactate levels during exercise (1–5)
reduced enzyme activity of muscle phosphofructokinase (PFKM) is detected resulting in impaired phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate
a more proximal defect in the glycolysis chain is present based on the defect of glycolytic enzyme myophosphorylase
We studied the lactate and ammonia profiles in two siblings with Tarui disease associated with symptom-limited maximal spiroergometric exercise testing. For comparison, two patients with McArdle disease and eight controls were studied. In defects of muscle metabolism, the level of lactate and/or ammonia associated with exercise may be altered depending on the character and location of the metabolic defect in the energy chain (5, 6)
We report here the differences found in exercise-induced metabolites in these different study groups
Patient Tarui 1 was a 58-year-old otherwise healthy man without regular medication
he began to experience strong attacks of muscle pain
and vomiting during extensive physical activity associated with increased CK levels
Mild muscle weakness was observed concentrating on hip flexors and extensors on both sides and ankle flexors and extensors on right side
the 57-year-old younger sister of patient Tarui 1 had similar symptoms as her brother since the age of 10
aged 35 (McArdle 1) and 20 years (McArdle 2) were studied
and muscle biopsy analysis showing non-lysosomal glycogen accumulations and a total lack of myophosphorylase staining were consistent with McArdle disease
a homozygous mutation of PYGM gene was detected in both of them (c.2056G > A; p.G686R in McArdle 1 and c.1A > G in McArdle 2)
For comparative analyses, eight healthy gender and age-matched control subjects were studied, the anthropometric characteristics are given in Table 1
The main results of spiroergometric exercise testing as well as the venous lactate and ammonia results associated with exercise testing in patients with Tarui disease (Tarui 1 and Tarui 2)
patients with McArdle disease (McArdle 1 and 2) and the controls
Informed consent was signed by the patients and controls and the study has been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments (The Medical Ethics Committee of Helsinki and Uusimaa Hospital District
The lactate and ammonia specimens were taken into fluoride oxalate and EDTA syringes
centrifuged and analyzed with a Cobas Integra 400 + analyzer (Roche Diagnostics
and lactate and ammonia ions were assayed by enzymatic methods using lactate dehydrogenase and glutamate dehydrogenase
The spiroergometric results are presented in Table 1
(A) The blood lactate levels associated with spiroergometric exercise testing in patients with Tarui disease and the results of two patients with McArdle disease are given
as well as the mean values of eight healthy controls matched to the age and gender of the patients
(B) The blood ammonia (NH4+) levels associated with spiroergometric exercise testing in patients with Tarui disease
the results of two patients with McArdle disease are given
as well as the mean values of eight control subjects matched to the age and gender of the patients
The healthy controls had normal exercise performance and oxygen uptake (Table 1)
and their RQ values at maximal exercise were clearly higher than 1
The lactate and ammonia values of the control subjects increased normally with a maximal increase of lactate and ammonia 2–6 min after exercise
the utilization of glycogen during anaerobic exercise is interrupted by the lack of PFKM leading to very low levels of lactate during exercise
in spiroergometric testing a late increase of lactate two to three times the basal value was seen at time points 10–30 min after exercise
this study demonstrates for the first time that exercise lactate profile distinguishes Tarui disease from McArdle disease
glycogen is metabolized via glucose 6-phosphate to fructose 6-phosphate
but in Tarui disease fructose 1,6-bisphosphate cannot be produced
a slight residual PFKM activity of 3–4% out of normal was found in enzyme activity analyses
which might lead to a slight increase of lactate during exercise
if the residual phosphofructokinase production would increase the lactate level
the lactate raise should start during exercise with a maximum level of lactate 2–4 min after exercise
and not at time points 10–30 min exercise as we here demonstrate
second wind phenomenon was observed only in patient McArdle 2
it is not likely that the late increase of lactate in Tarui disease would be associated with second wind phenomenon
Figure 2. Schematic presentation of the pathways of glycolysis modified from Ref. (18)
The main points of the glycolysis chains involved in Tarui disease and McArdle disease are presented
The black arrow indicates that glycolysis disrupted by Tarui disease can continue through pentose phosphate pathway (PPP) at glyceraldehyde-3 phosphate
The dotted arrow: fructose 6-phosphate accumulates because of Tarui disease
and its metabolism may continue in the PPP pathway
from where it may enter in protein or nucleic acid synthesis
Increase of synthesis of proteins or nucleotides means also increase of products of their metabolism
Some enzyme names and products of the glycolysis chain have been left away to get the figure more feasible to the present purpose
In some previous studies on Tarui disease, suggestions of a late lactate increase after exercise have been recorded, confirming our results (19, 20). In addition, findings that suggest increased glyceraldehyde-3 phosphate levels and alteration into the PPP route in Tarui disease during exercise have been published (3)
We report here for the first time a full-length spiroergometry study with follow-up of lactate and ammonia
as well as extended follow-up after exercise
comparing the results also with healthy controls
In McArdle disease, increased ammonia during exercise has previously been reported (4, 25–28), as also we found in patient McArdle 2. Compared to patient McArdle 2, patient McArdle 1 showed only slight increase of ammonia in exercise even though he reached maximal subjective level of 19/20. Earlier, Mineo et al. (19) have found corresponding slight ammonia responses in McArdle disease
Heterogeneity of McArdle disease might be one explanation for the observed variances in ammonia level
it is difficult to assess objectively the maximality of exercise in McArdle disease because the absent lactate response causes that ventilation is not stimulated normally during exercise
we show that Tarui disease is associated with low lactate levels during exercise with a late increase of lactate after exercise and exceptionally high ammonia levels during and after exercise
The particular lactate profile differentiates patients with Tarui disease from patients with McArdle disease and helps the clinician to choose proper genetic tests
and it suggests that further study should be performed on exercise glucose metabolism in patients with rare glycogen storage disorders
we recommend to utilize maximal bicycle spiroergometry with sufficiently long (30–40 min) follow-up of ammonia and lactate levels after exercise

The Crisil Coalition Greenwich 2024 Public Pension Defined Benefit Study sponsored by T
Rowe Price confirmed our expectations that defined benefit (DB) plans became overweight risk assets and have maintained this positioning despite broadly higher capital market assumptions (CMAs)
Our Solutions team analyzed the effects of historical CMAs and expected return on assets (EROAs) to understand how each could be impacting asset allocations now and how these allocations could evolve going forward
Our analysis indicates that plans could be in a position to meet their EROAs while lowering overall portfolio risk
Our mid-2024 Crisil Coalition Greenwich survey revealed that the average defined benefit plan had significant exposure to risk assets
Figure 1 highlights that many respondents were overweight their own equity targets
This finding was not surprising—over a decade of zero or near-zero interest rates hampering fixed income return potential contributed to this dynamic
What was somewhat surprising given the notable increase in available yields in recent years is that many allocations have remained overweight risk assets and underweight public fixed income
Figure 2 illustrates the period of near-zero interest rates that forced plans to increase equity allocations in an effort to achieve their targeted return goals
The sharp increase in interest rates in recent years has reversed this dynamic
yet many plans remain overweight equity and could consider reevaluating this positioning
Central bank rate hikes of 2022–2023 have led to higher-yielding fixed income assets
With our survey indicating that the majority of plans intended to hold EROAs steady
we evaluated how impactful increased CMAs could be to asset allocation possibilities
We simulated thousands of portfolio weights and constructed portfolios using 2020 and 2025 return assumptions to understand the impact that different return environments would have had on portfolios
Source: Crisil Coalition Greenwich 2024 Public Pension Defined Benefit Study
Figures inparentheses ( ) indicate number of respondents
approximately 2% of all the potential portfolios would have achieved the average pension EROA of 7%1 when using 2020 CMAs
This figure increases dramatically—to nearly 20% of all potential portfolios meeting the EROA target—when using 2025 CMAs that have risen as higher cash rates have increased fixed income yields across sectors
We estimate that revised asset allocations that increase exposure to fixed income can potentially reduce overall portfolio risk by nearly 20% while still achieving an ex-ante return profile that aligns with typical public plan EROAs
the average current allocation would generate an expected five-year return of 7%
which is in the middle of the stated range
we targeted the same return value while minimizing risk
increased allocations to plus-sector fixed income (bank-loans
distressed debt) would offset reductions in private equity
The results of our public defined benefit plan survey confirm that plans remain overweight risk assets; however
the current environment creates opportunities to reassess asset allocations
as there are more portfolio construction options that can deliver against return targets while lowering overall risk

Hawaiʻi representative Amy Perruso got her start in climate advocacy as a college student in California
going door-to-door to talk to community members about pollution
she says she sees that same sort of energy for climate action in young people today
“There's this element of idealism that is only coming from the younger generation,” said Perruso
“And it's that note that we really need to listen for and kind of align ourselves with.”
Perruso is one of the lawmakers who will participate in the student-organized Climate Future Forum this Saturday at the Hawaiʻi State Capitol
She’s no stranger to the political interests of young people — she taught high school social studies for decades before she became a representative
“I've worked with young people my whole life
“The moment of COVID was a break in what I saw working with young people in politics
a sophomore at ʻIolani School and one of the organizers of Saturday’s Climate Future Forum knows that firsthand
she turned to activism to fight feelings of powerlessness during the pandemic
“The pandemic… was a moment of realization for me,” said Lin
just forces you to change your entire lifestyle and change the way that you communicate with people
reaching out to outlets where we can make a difference is really important.”
Fellow ʻIolani sophomore and organizer Chisato Tarui is looking forward to digging into the nitty-gritty of climate policy with lawmakers during the forum
But she understands that might not be every student's idea of a laid-back Saturday
“We're going to have legislators there in the workshops
and that may be intimidating for a lot of young people
I know I would be intimidated by that,” said Tarui
The workshops will be student-led so that newcomers feel welcome in the conversation
Tarui and Lin along with other organizers will take the lead in introducing concepts like carbon pricing and intersectional justice to their peers
“Having a young person teach something to another person of youth
I think that in itself is going to be an incredibly accessible way to reach out to them,” said Tarui
Lin hopes the forum will encourage young people to participate in the legislative process
She remembers how nervous she was the first time she met with a lawmaker
“And I walked in…and I was greeted with a person,” said Lin
“And I think that made me realize that these people who are
and the only thing that we need to do to make our voices heard is just to talk to them.”
Tarui also hopes more students start to recognize they are an important political force
we're still like 16 years old… but we still very much have a voice,” said Tarui
Perruso would like to see this effort go a step further. She’s been an advocate for the Vote16 movement, which would lower the voting age to 16-years-old, opening up the democratic process to students like Tarui and Lin.
“We've created a situation that has made it necessary for them to be fully participating citizens at an earlier age,” said Perruso. “So we have the responsibility, I think, to grant them that actual power.”
Background: A deficiency of muscle phosphofructokinase (PFKM) causes a rare metabolic muscle disease, the Tarui disease (Glycogen storage disease type VII, GSD VII) characterized by exercise intolerance with myalgia due to an inability to use glucose as an energy resource. No medical treatment for GSD VII currently exists. The aim of this study was to determine whether a dietary intervention with excessive fat intake would benefit GSD VII.
Results: During the 5 years on KD, the patient's muscle symptoms had alleviated and exercise tolerance had improved. In exercise testing, venous ammonia had normalized, the lactate profile remained similar, but oxygen uptake and mechanical efficiency had increased and parameters showing ventilation had improved.
Conclusions: This study is the first to show a long-term effect of KD in GSD VII with an alleviation of muscle symptoms, beneficial effects on breathing, and improvement in exercise performance and oxygen uptake. Based on these findings, KD can be recommended under medical and nutritional supervision for selected patients with GSD VII, although further research of this rare disease is warranted.

Background: A deficiency of muscle phosphofructokinase (PFKM) causes a rare metabolic muscle disease
the Tarui disease (Glycogen storage disease type VII
GSD VII) characterized by exercise intolerance with myalgia due to an inability to use glucose as an energy resource
No medical treatment for GSD VII currently exists
The aim of this study was to determine whether a dietary intervention with excessive fat intake would benefit GSD VII
Patient and Methods: A ketogenic diet (KD) intervention implemented as a modified Atkins diet was established for one patient with PFKM deficiency
with a low late lactate response and very high ammonia levels associated with exercise
We recorded the KD intervention for a total of 5 years with clinical and physiotherapeutic evaluations and regular laboratory parameters
including breath gas analysis and venous lactate and ammonia measurements
8 months and 5 years after initiation of KD
the patient's muscle symptoms had alleviated and exercise tolerance had improved
but oxygen uptake and mechanical efficiency had increased and parameters showing ventilation had improved
Conclusions: This study is the first to show a long-term effect of KD in GSD VII with an alleviation of muscle symptoms
and improvement in exercise performance and oxygen uptake
KD can be recommended under medical and nutritional supervision for selected patients with GSD VII
although further research of this rare disease is warranted
The patient is a 59 years-old man carrying a homozygous PFKM gene mutation, c.329G>A. The histological and genetic findings (9) and the analyses of the exercise lactate profile (10) have been published earlier
he had normal motor development and normal exercise tolerability
As a young boy he could run up to 100 meters but around the age of 12 years he started to develop symptoms
He was never hospitalized due to the muscle symptoms or due to raise in creatine kinase (CK) values
At age 59, there was mild muscle weakness in hip flexors and extensors and ankle flexors and extensors on the right side [MRC scale 4 out of 5 (11)]
Medication for high blood pressure had been recently introduced (amlodipin 5 mg and valsartan 160 mg once a day)
The patient's weight was 71 kg and height 177 cm (BMI 23.0 kg/m2)
He could walk with a slow pace about 10 km but walking on an incline was limited by muscle pain
because of muscle cramping and feeling unwell
He did regular hunting and hiking trips in the forest
He annually spent 4–5 days in Lapland with a group of friends hiking 15–20 km daily but he was always the last in the group and other members had to wait for him
Ethical approval for the study was granted by the Medical Ethics Committee of Helsinki University Central Hospital
Informed consent was provided by the patient and the controls
The patient's diet was evaluated using a 3 days food record prior to KD initiation, and the evaluation was repeated 6 months after starting KD. Dietary intakes were calculated using the national food composition database of the National Institute for Health and Welfare, Finland (12)
The KD was guided by the same dietitian (M.S.) throughout the study period
Nutrition and diet were assessed and counseled at clinic visits or by phone or email contacts several times during the initiation period and later at least yearly
Daily energy intake was planned to be at the same level as before the KD
the amount of carbohydrates was restricted to 10 g per day
and the consumption of fat and protein was encouraged
aiming at a ketogenic ratio of ~1:1
Consumption of unsaturated fats was recommended to avoid unfavorable changes in serum lipids
and calcium supplementations were introduced
Temporal mitigation of carbohydrate restriction (using small or moderate amounts of e.g.
rye bread) was allowed during the treatment when disadvantage of the diet was considered (strong increase of LDL-cholesterol)
Laboratory parameters were followed up regularly; e.g., β-hydroxybutyrate, glucose, cholesterol, CK, and liver function were measured almost monthly during the first year and, after stabilization of the diet, twice during the second year and once a year thereafter, except for cholesterol values, which were measured more often. The laboratory results from the time points of exercise testing are presented in Table 1
concentrations of some vitamins (vitamins D and A)
and urine calcium and creatinine were measured discretionarily to optimize nutrient intakes
Blood β-hydroxybutyrate was also measured by the patient at home to ensure ketosis (target level 2.5–5)
at the beginning every morning and evening
Laboratory parameters before ketogenic diet (KD) and during the 5 years follow-up at the time points of cardiopulmonary exercise testing
Younger men and women from the original controls were excluded
Spearman's correlation test was performed between the baseline and diet phases for the patient as well as for the controls
the calculated total energy intake was 2,660 kcal per day and consisted of 177 g of available carbohydrates (27 E%
107 g of protein (16 E%) and 164 g of fats (55 E%)
the calculated total energy intake was ~2,880 kcal per day and consisted of 229 g of fats (72 E%)
189 g of protein (26 E%) and 12 g of available carbohydrates (2 E%)
Vitamin D concentration (serum 25-hydroxyvitamin D3 and D2) was at the beginning of dietary therapy below reference values
Already after 6 months' exposure to KD
the patient began to experience a subjective alleviation of muscle symptoms
manifesting as more rapid recovery and less muscle discomfort
He was able to increase daily exercise and could gradually spend extended periods of time hiking and hunting in the forest
his muscle strength (MRC) was within the normal range (5 of 5) except for ankle extension forces (4 of 5)
Deep tendon reflexes were present excluding Achilles
He felt that exercise tolerance had improved during KD and experienced less cramping and nausea during exercise than before KD
He could now walk longer without stopping and could ski 10–15 km/day at the same speed as his friends
During KD he could participate in long hiking trips
He felt that especially capability to walk on an incline was better than before KD
The patient's weight had decreased from 71 to 58 kg (height 177 cm)
with BMI falling from 22.7 to 18.5 kg/m2 in 5 years
The main results of the cardiorespiratory exercise testing during the follow-up at the time points of 3, 8 months and 5 years are presented in Table 2
The maximal working capacity was moderately reduced before KD
but it remained lower than the values of age-matched controls
The maximal oxygen uptake by body weight had a mild increase during KD and the mechanical efficiency (Wmax/VO2max) increased from 13.1 to 16.5% (normal value ≥20%)
Results of cardiorespiratory exercise testing of the patient before and during KD
During KD a decrease occurred in the very high maximal breathing frequency in exercise
from 68 to 46/min and an increase in tidal volume from 44.6 to 60.3% of predicted value
as assessed in slightly increased minute ventilation vs
CO2 production (VE/VCO2) and O2 consumption (VE/VO2) and also in slightly decreased FetCO2
Figure 1. Lactate levels associated with exercise tests of the patient before diet and during the follow-up. The values of the control subjects without dietary intervention are also given for comparison. The baseline lactate data has been published earlier (10)
the controls matched to the age and gender of the patient were obtained from the forementioned publication
A strong correlation existed between the patient's baseline lactate values and his diet curves at 3
Figure 2. Ammonia levels associated with exercise tests of the patient before the diet and during the follow-up. Values of the control subjects without dietary intervention are also given for comparison. The baseline ammonia data has been published earlier (10)
and the controls matched to the age and gender of the patient were obtained from the aforementioned publication
No correlations existed between the baseline curve of the patient and those of the controls or the diet curves of the patient
Figure 3. pH levels associated with exercise tests of the patient before the diet and during the follow-up. Values of the control subjects without dietary intervention are also given for comparison. The baseline ammonia curve has been published earlier (10)
A high negative correlation existed between the patient's baseline curve and mean diet curve (rho = −0.826
During the 5 years follow-up of KD the patient remained clinically stable with subjective alleviation of muscle pain symptoms and better exercise tolerance
working capacity and mechanical efficiency had increased
lactate levels had decreased from the low pre-KD levels
and the very high ammonia levels associated with exercise testing detected in the measurements before KD had decreased to normal
KD had a beneficial impact also on respiratory parameters during exercise
reflected as lowering of breathing frequency and the ventilatory equivalent for O2 (V′E/O2) and as increasing tidal volume
the end tidal CO2 level (FetCO2) remained rather low
indicating permanent hyperventilation tendency
possibly attenuating our findings on the beneficial effects of KD
The patient's original diet was evaluated for the first time before the initiation of KD
KD was fairly well-tolerated by the patient
high LDL-cholesterol level was measured (4.9 mmol/L)
Since cardiovascular disease exists among the patient's immediate family
the disadvantage of the KD for the patient was reconsidered
and the restriction of carbohydrates was mitigated (e.g.
Based on the patient's subjective experience of lowered exercise capability after the increase of carbohydrates
With rising LDL-cholesterol values (up to 6.2 mmol/L) cholesterol-lowering medication was started after 3 years of KD
The LDL-cholesterol level was at the 5 years control lower than before KD (2.1 vs
no abnormalities were detected in the liver or kidney functions
The patient's weight decreased by 13 kg during KD
although it was not the original aim of the treatment
the reported energy intake during KD was greater than before KD
This may be due to the better working capacity
leading to increased physical activity during the diet
it is also possible that the difference between these calculated intakes is explained by normal day-to-day variation in food intake since the food record periods were short (3 days)
Just before the exercise test at 8 months the patient returned to ketosis, and in the exercise test, a new increase in ammonia was detected. This suggests that even a short period of more carbohydrates may increase the ammonia level during the exercise test (Figure 2) highlighting the importance of carbohydrates in the high ammonia levels associated with Tarui disease
Since convincing evidence between higher whole-grain consumption, which is a substantial contributor to carbohydrate intake, and lower risk of coronary heart disease, type 2 diabetes, colorectal cancer and all-cause mortality, is growing (29)
extreme restriction of carbohydrates has to be well-founded
The risk factors of chronic diseases must be considered during long-term KD as was done in our case
with cholesterol-lowering medication started due to the increase in LDL-cholesterol levels
The patient felt that his exercise capability was decreased in conjunction with increased carbohydrate intake and wanted to continue the strict KD with subsequent initiation of cholesterol medication
During KD associated with the exercise test
pH and base excess values remained rather high
indicating that no metabolic acidosis had developed
Carbohydrate intake restriction and ingested fat and proteins produce acidic ketones
which have a tendency to advance to metabolic acidosis; however
This is probably explained that there still would have been release of alkaline ammonia from protein catabolism
The main strength of this study is that KD was carefully implemented and followed in a very cooperative patient
Laboratory examinations were performed continuously
the follow-up intervals increasing as the patient achieved a balance with KD
Also the cardiorespiratory exercise testing was first performed with shorter intervals
and the last test at 5 years to obtain data on long-term KD treatment
A study limitation is that we had only one patient
KD intervention in our patient with Tarui disease seemed to have a beneficial effect
as measured by the patient's subjective condition with diminished muscle symptoms and increases in exercise capacity and oxygen uptake
which also had a favorable effect on the patient's ventilation
but with statin medication the levels were kept under control
Our results thus encourage the implementation of KD in patients with Tarui disease as the risk factors of chronic diseases are considered

Phosphofructokinase deficiency is a very rare autosomal recessive disorder
which belongs to group of rare inborn errors of metabolism called glycogen storage disease
Here we report on a new mutation in the phosphofructokinase (PFK) gene PFKM identified in a 65-years-old woman who suffered from lifelong intermittent muscle weakness and painful spasms of random occurrence
After ruling out the most common causes of chronic haemolytic anemia
the study of a panel of 24 enzyme activities showed a markedly decreased PFK activity in red blood cells (RBCs) from the patient
DNA sequence analysis of the PFKM gene subsequently revealed a novel homozygous mutation: c.926A>G; p.Asp309Gly
This mutation is predicted to severely affect enzyme catalysis thereby accounting for the observed enzyme deficiency
This case represents a prime example of classical PFK deficiency and is the first reported case of this very rare red blood cell disorder in Spain
Phosphofructokinase (ATP: D- fructose-6-phosphate-1-phosphotransferase; EC 2.7.1.11; PFK) is a key regulatory enzyme of the glycolytic cycle and catalyses the conversion of fructose-6-phosphate to fructose-1,6-diphosphate (Figure 1). Human PFK is composed of three isoenzymes, muscle (M), liver (L), and platelet (P) (Vora, 1983; Nakajima et al., 2002)
The P type is also known as Fibroblast type (F)
Mammalian PFK is a tetrameric enzyme that is subjected to allosteric regulation
Tissue isozymes randomly aggregate to form homotetramers or heterotetramers depending on the relative abundance of the subunits in a particular tissue
PFK-M is the sole subunit in muscle cells whereas red blood cells (RBCs) contain both L and M subunits and form their hybrids (M4

Phosphofructokinase deficiency (OMIM 171 850) is a very rare autosomal recessive condition with heterogeneous clinical symptoms, mainly characterized by myopathy and/or haemolysis (Hirano and Di Mauro, 1999)
Myopathy is caused by the accumulation of glycogen in muscle tissue due to the metabolic defect and is also known as glycogenosis type VII or Tarui disease
The observed clinical symptoms reflect lack of muscle PFK activity and partial reduction of enzymatic activity in erythrocytes
The latter usually is associated with mild haemolysis
Up to now, only about 100 patients with PFK deficiency have been reported worldwide and 22 PFK-deficient PFKM alleles have been characterized. The gene encoding the M subunit (PFKM) has been assigned to chromosome 12q13.3 and spans 30 kb. It contains 24 exons and at least 3 promoter regions (Elson et al., 1990; Yamada et al., 2004)
Among the detected mutations are mostly missense mutations and splicing defects
We now describe here a Spanish patient with a clinical history of anemia
who was found to be homozygous for a novel mutation in the PFKM gene (c.926A>G)
This mutation encodes the substitution of aspartic acid by glycine at residue 309 (p.Asp309Gly)
This is the first description of PFK deficiency in Spain
A 65-years-old woman with long standing hypertension and type 2 diabetes was referred to our Unit because of intolerance to exercise and chronic fatigue
From youth she suffered from spasms of random occurrence associated with muscle weakness
especially after exercise due to myoglobinuria
Physical examination showed no weakness or muscle atrophy and only a moderate splenomegaly without hepatomegaly or lymphadenopathy
Parents were unavailable for study and there was no known consanguinity
was present in a non-smoker brother whereas the three patient's daughters were normal
Patient's clinical condition has remained stable in follow-up
Red blood cell enzyme activity measurements
The complete lack of PFK activity in muscle was confirmed on both histological preparations and muscle extracts
Muscle abnormality was also confirmed by electromyography (EMG)
that showed mild myopathic changes and by the forearm test
characterized by a plane lactate curve with normal increase of ammonium
a painful spasm occurred at the end of the forearm test
Muscle biopsy showed slight amounts of polysaccharide (PAS) not digested by diastase and abnormalities in NADH-TR reaction
We therefore postulate that decreased binding of the allosteric activator ADP will inhibit PFK enzymatic activity
These findings support the physiological importance of Asp390 for the recently identified ADP binding site
3D crystal structure of PFK subunit from rabbit skeletal muscle and 3D model of normal/mutated PFKM (PDB 3O8L—protein databank)
(A) Allosteric nucleotide (ADP) binding site residues (purple) in the center of the rabbit subunit of PFKM
and the allosteric activator ADP are shown (atom coloring: carbon—green
(B) Close-up of the c.Asp309Gly mutation in PFKM
Asp309 is in close proximity of the ADP binding site
Asp309 does not directly interact with ADP
substitution of Asp309 by glycine is likely to disrupt multiple hydrogen bonds with Gly177
and the change of polarity and electrostatic interactions upon mutation of Asp309 will likely affect correct positioning of the side-chains of amino acids directly involved in ADP binding; in particular neighboring residue Phe308
which makes stacking interaction with the adenine ring of ADP
The missense mutation is thus predicted to lead to a less functional PFK-M subunit
the complete lack of PFK activity in muscle was confirmed on both histological preparations and muscle extracts
The muscle abnormality was also confirmed by electromyography
partial red blood cell PFK deficiency was reflected by the moderately decreased enzymatic activity in red blood cells
haemolysis is a result of partial erythrocyte PFK deficiency
the genetic defect involves the M isoform of PFK enzyme
resulting a severe enzyme deficiency in muscle
Erythrocytes that normally have two homotetramers (M4 and L4) and three hybrid isozymes (M3L
lack the M4 isoform and the hybrid isozymes
resulting in about 50% of normal PFK activity
Despite PFK deficiency is a very rare autosomal recessive disease; its true incidence may be higher due to lack of recognition
because the mild clinical presentation led her to be diagnosed
until the consideration of dark urines ultimately led to the study of chronic haemolysis
In our case the combination of RBC enzyme activity measurements and muscle biopsy analysis allowed for the correct diagnosis even at this late stage of life
no specific treatment or cure of enzyme deficiency exists
Although diet therapy may be highly effective at reducing clinical manifestations
the condition does not progress to severe disability
Because the liver and kidneys express only the L isoform
The here described homozygous patient is the first Spanish case described to be affected by this very rare disease
The identification of a novel homozygous missense mutation further extends the repertoire of PFK deficiency-associated mutations in PFKM

Climate change has recently been receiving significant and nervous attention from around the world
Some countries and regions have adopted carbon pricing such as carbon taxes and emissions trading as countermeasures against global warming
there is a concern about cross-border carbon leakage when a country introduces carbon pricing
Even if carbon emissions decrease in that country as a result of carbon pricing
carbon leakage increases carbon emissions abroad
and in some cases even increases global emissions
Cross-border carbon leakage undermines a country’s attempt to deal with climate change
The literature has identified the following three main channels of carbon leakage
International trade and foreign direct investment (FDI) exert an important influence on the channels explained above
many studies that analyse the effects of emission regulations from a global perspective incorporate international trade and FDI
most of those studies do not consider international transport
Those that address the interaction between trade
and the environment assume that the freight rates are exogenously given without an explicit model of the transport sector (e.g
the amount of carbon emissions created by international transportation itself is too large to ignore
According to the International Maritime Organisation
international transport emitted approximately 920 million tonnes of CO2 in 2018
surpassing Germany's national emissions (the sixth-highest emission in the world)
did not set specific targets for emissions from international transportation
leaders of several countries and industry associations delivered a series of statements regarding global warming countermeasures related to international transport:
we theoretically analyse the effect of unilateral carbon pricing on carbon emissions from production
and international transport by explicitly modelling the international transport sector
Our model is based on the endogenous transport cost literature
which has found that the international transport sector is highly concentrated
with transport firms having market power (Hummels et al
The transport firms charge asymmetric freight rates on shipping in different directions on the same trade route subject to the backhaul problem
The backhaul problem arises when the transport firm's shipping capacity is not utilised at the maximum level on the backhaul because of asymmetry in trade volumes
endogenous determination of international transport volumes and prices explains a new mechanism of cross-border and cross-sector carbon leakage
Figure 1 Top 10 deep-sea container shipping lines
ranked by deployed capacity and market share
Source: UNCTAD Review of Marine Transport 2020
Figure 2 Inter-regional contract freight rates
The effectiveness of carbon pricing depends on the presence or absence of a backhaul problem
If the exports from country A to country B (the fronthaul) exceed those from country B to country A (the backhaul)
The equilibrium freight rate on exports from B to A is then independent of the marginal costs of shipping (Ishikawa and Tarui 2018)
even though carbon pricing in shipping raises the effective marginal costs of shipping
it affects the freight rates in an asymmetric manner when the backhaul problem is present
carbon pricing on the transport sector reduces the fronthaul but affects neither the backhaul nor the associated emissions
We show that unilateral carbon pricing on goods consumption is effective
carbon pricing on goods production results in ‘positive’ cross-border carbon leakage: country A's carbon pricing on production lowers the fronthaul but increases the production in country B and the backhaul
and hence generates positive cross-border carbon leakage
but the endogenous increase in the freight rate mitigates them
meaning the behaviour of transport firms weakens cross-border carbon leakage
we find that both cross-border and cross-sector carbon leakage caused by carbon pricing can be ‘negative’
carbon pricing can be exceptionally effective because carbon pricing on a sector in a trading country may reduce emissions not only from the target sector but also from other sectors including those in other trading countries
carbon pricing on shipping increases freight rates for both directions
leading to the decrease in both fronthaul and backhaul
emissions not only from the transport firm but also from the manufacturing firms can decrease
implying that negative ‘cross-sector’ carbon leakage can occur
This observation identifies a new source of carbon leakage due to endogenous transport costs
We also show that if the backhaul problem is absent
any carbon pricing is effective because the global greenhouse gas emissions necessarily decrease
Our analysis also indicates that carbon pricing on international transport may not reduce overall trade-related emissions once we consider the interplay between endogenous transport costs and manufacturers' decisions on FDI
Faced with a manufacturer that may engage in horizontal FDI (i.e
the carrier may deter it strategically because the demand for transport decreases if horizontal FDI does not induce any trade in intermediate inputs
it prefers FDI with a single foreign plant to FDI with two plants (a domestic and foreign plant) because there is no demand for international transport with two-plant FDI
the carrier has an incentive to induce single-plant FDI
These strategic moves by the carrier also affect the global emissions
These findings follow from our theoretical framework
which addresses the interlinkage between trade
and environment by considering the transport sector explicitly
They indicate another benefit of comprehensive regulation of emissions from both production (or consumption) and transport
We argue that it is important to understand the market environment of the international transport sector when designing carbon pricing
the backhaul problem impairs not only the efficiency of transportation but also the effectiveness of carbon pricing
The effectiveness of carbon pricing will increase if policies can be taken to eliminate the backhaul problem at the same time as carbon pricing

Licca-chan is known as “Japan’s Barbie,” and her appeal is spreading to all ages
with adults turning the doll into a social media superstar
One fan posts wry videos of the plastic poppet to more than 1 million Instagram followers
while others painstakingly craft miniature clothes and share photographs of their fashion shoots
a 34-year-old homemaker who once had ambitions of becoming a fashion designer
said that her “dream has come true at one-sixth of the size” thanks to Licca-chan
“If I see a stylish woman wearing something that I couldn’t wear because of my age or body size
Licca-chan can still wear it and look good,” said Murayama
who owns about 40 dolls and has made more than 1,000 outfits for them
Licca-chan has been a favorite of Japanese children since she appeared in toy shops in 1967
and manufacturer Takara Tomy has sold more than 60 million of them
The company’s official biography casts her as an 11-year-old girl with a Japanese designer mother and a French musician father
she is smaller and less glamorous than Barbie
who Murayama describes as “a supermodel” compared with Licca-chan’s more “familiar” look
Murayama spends hours making clothes for her dolls and favors denim
which her husband helps her bleach and tear to achieve the “distressed” look
using tiny props to decorate mini cafes and fashion studios
“There are lots of different jobs I would like to do
such as running a cafe or a bakery or being a fashion designer,” she said
there’s no way I could do them all in real life
Murayama is a fan of a popular social media channel whose name translates as “Licca-chan’s Real Life.”
It features tongue-in-cheek videos and photographs of the doll in mundane situations
such as struggling with an overstuffed rubbish bag or relaxing at home in pyjamas
The channel offers an antidote to the idealized lives that people project online
who has more than 1 million Instagram followers
but prefers to remain anonymous so that her videos do not get her into trouble at work
“The Licca-chan in Licca-chan’s Real Life doesn’t live a glamorous life — she lives a real life in a messy room
“If you show people that even someone like Licca-chan lives like that
it gives them the courage to be comfortable with themselves.”
Takara Tomy is not keen on Licca-chan’s Real Life
saying the videos have “a different worldview” from their fiercely protected official image of the doll
but the channel has struck a chord with Licca-chan’s adult fans
who have formed an online community and swap homemade garments and accessories
played with Licca-chan as a child and revived her interest about two years ago as a way to relieve stress
She thinks the lingering effects of the COVID-19 pandemic have given people more time to spend at home with their hobbies and less chances to leave the house
you have far fewer opportunities to buy new clothes,” she said
adding that many people have “satisfied that desire by dressing up dolls instead.”
Baba often recreates outfits from her own wardrobe for her dozens of dolls to wear
Takara Tomy is aware of its growing adult fan base and has launched a “stylish doll collection” aimed at older customers
Maruyama said “there are lots of adults who play with kids’ toys” in Japan where “there’s not really a separation” between the two
who describes Licca-chan as a “national icon,” believes the doll’s appeal will only grow
“Recently I’ve seen a lot of comments from people saying they didn’t know that this world existed,” she said
one of the world's largest and most successful hedge funds
is well-known for the cultural quirks instilled by founder Ray Dalio
who insists on "extreme openness" and "radical transparency" in a 100-page manifesto titled Principles
An employee who accused the firm of mishandling his harassment complaint
describes the atmosphere very differently
"The company's culture is nothing more than a cauldron of fear and intimidation achieved by constant surveillance -- audio and visual recording of every employee interaction and security guards patrolling both office floors," the employee says in an affidavit obtained by The Street
which was filed with Connecticut's Commission on Human Rights and Opportunities in January
The claims were first reported by the New York Times
Bridgewater Client Advisor Christopher Tarui described a pattern of sexual harassment from a male supervisor and said a meeting he had with a human resources staffer regarding his concerns was taped and "widely shared" among co-workers.
Tarui, 34, joined Bridgewater in 2011, moving from California with his wife and young family for the job. His first sign of trouble at the hedge fund came two years later
on a 2013 business trip with the supervisor
who was also a married man with young children
Tarui said he went to a strip club with the manager and watched as the manager had "sexual intercourse with a stripper." The supervisor later told Tarui ("preposterously," Tarui notes) that he felt "taken advantage" of by the exotic dancer
the two Bridgewater employees were on a business trip in Denver

Tarui said that the team leader "caressed the small of my back," which "made me feel extremely uncomfortable." Tarui departed the room hastily saying he needed to sleep
but said that his colleague was undeterred
and sent a text message urging him to come back
the two men were staying at a Boston hotel when the supervisor "brazenly explained" that he had "an itch to scratch," asking his married coworker if he ever "thought about being with other men," and going on to specifically request the two men share "a sexual experience," Tarui said
replying that he was "not wired that way," and "did not want to be with a man," but noting that he made "no judgment" regarding his college's desires
Fearing personal humiliation and anxious about his future with Bridgewater
Tarui said he kept the matter to himself until last summer
when his "worst fears" came true
and the supervisor rated his performance poorly and began to suggest other career options
"I realized I could no longer keep silent about what was happening to me," Tarui said
and described the alleged harassment in a meeting that
acknowledges that there are "some times when privacy is required," but recommends taping nearly all meetings and sharing them with all relevant people
An outside spokesperson did not respond to request for comment
but the company in an e-mailed statement to the New York Times said "we are confident our handling of this claim is consistent with our stated principles and the law ..
We look forward to operating through a legal process that brings the truth to light."
though many employment contracts require closed arbitration
Tarui's complaint was withdrawn from the Connecticut employment oversight agency in March after a request he and Bridgewater filed jointly
Matters came to a head for Tarui in December
when he said he declined a senior manager's request to describe his "personal journey" at Bridgewater in connection with an upcoming "Quality Day" meeting
"A majority of 'Quality Day' is devoted to subjecting junior employees to rapid-fire questions
regarding a wide range of investment and socio-cultural topics as well as questions about Principles
in front of approximately 200 of their colleagues," according to Tarui
Another senior manager confronted Tarui that evening
on the sidewalk outside the New York Public Library in Manhattan
""Nothing happened to you," Tarui claims the manager told him
"You are blowing this whole thing out of proportion."
two days before filing the complaint with the state
Tarui was placed on paid leave from Bridgewater and escorted out of its offices in Westport

Metrics details
Metabolic myopathies are muscle disorders caused by a biochemical defect of the skeletal muscle energy system resulting in exercise intolerance
The primary aim of this research was to evaluate the oxygen cost (∆V’O2/∆Work-Rate) during incremental exercise in patients with metabolic myopathies as compared with patients with non-metabolic myalgia and healthy subjects
The study groups consisted of eight patients with muscle glycogenoses (one Tarui and seven McArdle diseases)
seven patients with a complete and twenty-two patients with a partial myoadenylate deaminase (MAD) deficiency in muscle biopsy
five patients with a respiratory chain deficiency
seventy-three patients with exercise intolerance and normal muscle biopsy (non-metabolic myalgia)
The subjects underwent a cardiopulmonary exercise test (CPX Medgraphics) performed on a bicycle ergometer
Pulmonary V’O2 was measured breath-by-breath throughout the incremental test
The ∆V’O2/∆Work-Rate slope for exercise was determined by linear regression analysis
Lower oxygen consumption (peak percent of predicted
one-way ANOVA) was seen in patients with glycogenoses (62.8 ± 10.2%) and respiratory chain defects (70.8 ± 23.3%) compared to patients with non-metabolic myalgia (100.0 ± 15.9%) and control subjects (106.4 ± 23.5%)
∆V’O2/∆Work-Rate slope (mLO2.min−1.W−1) was increased in patients with MAD absent (12.6 ± 1.5)
and patients with non-metabolic myalgia (11.3 ± 1.3) compared with control subjects (10.2 ± 0.7; p < 0.001
patients with metabolic myopathies display an increased oxygen cost during exercise and therefore can perform less work for a given VO2 consumption during daily life-submaximal exercises
little is known about oxygen cost of exercise in myoadenylate deaminase (MAD) deficiency
case-control studies have been mostly employed
by selecting patients with a given diagnosis of metabolic myopathy
but for whom exercise intolerance may not be the chief complaint
This shortcoming is prevented by consecutive inclusion of patients consulting for exercise intolerance and exercise-induced myalgia
The primary aim of this research was therefore to evaluate the oxygen cost during incremental exercise in different metabolic myopathies compared with patients with non-metabolic myalgia and healthy subjects
using a standardized methodology in a prospective-unselected cohort
Table 2 summarizes the baseline characteristics and the results of exercise testing for the five subgroups of patients and the Control group
Age and BMI were similar among groups (p = 0.598 and 0.265
One-way ANOVA showed a main effect of group for exercise duration [F(5,137) = 2.94; p = 0.015]
but Games-Howell post-hoc tests did not identify significant differences between groups
was significantly different between the six subgroups [F(5,137) = 17.61; p < 0.001
Post-hoc pairwise comparisons from the Scheffé test revealed that % Predicted maximal power was significantly lower in Glycogenoses compared with healthy controls (p < 0.001)
% Predicted maximal power was significantly reduced in RCD group compared with Controls (p < 0.001)
the average peak oxygen consumption achieved was 20.1 ± 7.8 mLO2.min−1.kg−1
representing 62.8 ± 10.2% of the age-predicted value
The latter result was less than for Controls (p < 0.001) and Non-metabolic myalgia (p = 0.007)
Scheffé post-hoc test revealed a significant lower percentage of predicted peak V’O2 achieved compared to Controls (p < 0.007) and Non-metabolic myalgia (p = 0.036)
Oxygen cost of exercise in metabolic myopathies
Data were analyzed using a one-way ANOVA with post hoc Games-Howell test for intergroup analysis
*Significantly different from Control (p < 0.04)
% Predicted maximal heart rate (HRmax) was significantly lower in MAD Absent group compared with Control (p = 0.005) and Non-metabolic myalgia (p = 0.007) groups
peak O2 pulse was significantly decreased compared with Control (p = 0.005) and Non-metabolic myalgia (p < 0.001) groups
The metabolic-chronotropic relationship (MCR) in the MAD Absent group (0.58 ± 0.18) was significantly lower than in the Control (p = 0.01)
the MCR of Glycogenoses (1.50 ± 0.29) was significantly higher than the MCRs of all other groups
The respiratory exchange ratio (RER) was similar between groups at rest
and was found to be significantly less in Glycogenoses at peak exercise (0.91 ± 0.03) compared with all other groups (p < 0.02)
Control group demonstrated a significantly higher RER at peak exercise (1.27 ± 0.06) than other groups (p < 0.04) with the exception of RCD group (1.25 ± 0.12
Peak V’E/V’O2 and V’E/V’CO2 slope were not significantly different between groups (p = 0.075 and 0.059
Post-hoc tests for oxygen uptake efficiency slope (OUES) and peak V’E/V’CO2 revealed no significant difference between groups
Lactate concentration at rest was significantly lower in Glycogenoses (0.8 ± 0.3 mM) compared with Control (p = 0.01)
lactate was significantly lower in Glycogenoses (0.9 ± 0.3 mM) compared with all other groups with the exception of MAD Absent (3.1 ± 1.6 mM
Patients with absence of MAD activity showed lower lactate concentration at peak exercise compared with Control (p = 0.011) and Non-metabolic myalgia (p = 0.016) groups
was significantly higher in Glycogenoses (112.5 ± 50.5 µM) compared with all other groups (p < 0.05)
with exercise testing performed and reported in a standardized fashion
The present prospective methodology permits comparison both across different metabolic myopathies and with non-metabolic myalgia during incremental exercise
Visual inspection of the plots in Fig. 2 reveals two distinct profiles in patients
A first group of metabolic myopathies that includes MAD absent
and mitochondrial myopathy exhibits a large increase in ∆V’O2/∆WR slope (12.4–14.2 mLO2.min−1.W−1
A second profile includes MAD decreased and non-metabolic myalgia
with moderate increase in mean ∆V’O2/∆WR slope
due to substantial overlap in ∆V’O2/∆WR slope values between groups
post-hoc tests failed to detect statistical differences between subgroups of patients
Reasons for the disparity in ∆V’O2/∆Work-Rate slope in RCDs among studies deserve further investigation
The increased work by respiratory muscles in patients with glycogenoses and RCD requires higher oxygen consumption to maintain this activity and may contribute to increase the ∆V’O2/∆Work-Rate slope
due to the lower ATP produced/oxygen consumed ratio when lipid is the substrate
Due to the prospective design of our study
a single –standardized- incremental exercise protocol involving a 2-min warm-up was used in all subjects
the extent to which the ‘second-wind’ mechanism contribute to the increased MCR and the greater ∆V’O2/∆Work-Rate slope in glycogenoses remains unknown
Although the reduction of peak oxygen consumption is moderate in MAD Absent patients
their greater ∆V’O2/∆Work-Rate slope may reduce exercise tolerance by increasing perceived effort
Patients with metabolic myopathies exhibit a greater oxygen cost of exercise
The clinical implication of this exacerbated oxygen cost of power production is that a patient with metabolic myopathy can perform less work for a given VO2 consumption during daily life-submaximal exercises
This loss of efficiency could partially explain difficulties to maintain exercise in metabolic myopathies owing to increased perceived effort
Written informed consent was obtained from each participant
All procedures conformed to the standards set by the Declaration of Helsinki and the protocol was approved by the institutional ethics committee of Brest Medical University Hospital (Clinical Trial NCT02362685)
Myoadenylate deaminase staining was absent in seven patients and decreased in twenty-two subjects
Respiratory chain deficiency (RCD) group (n = 5) consisted of two patients with MELAS syndrome (m.3243 A > G MTTL1 gene mutations)
and three patients with characteristic abnormalities of mitochondrial cytopathy (ragged-red and COX-negative fibers) and decreased complex IV activity in muscle biopsy specimen
were recruited as a disease-control group (non-metabolic myalgia)
referred for fitness for work evaluation in our department during the study period
Data from the 1st minute of loaded exercise were discarded from analysis
owing to the initial –exponential- delay of VO2 increase at the onset of work
All statistical analyses were conducted two-tailed with α set at 0.05 and were computed using SPSS (V.25; IBM SPSS Statistics
Assessment of data normality was determined by Shapiro–Wilk test
Between-group differences were assessed using One-way ANOVA followed by Scheffe’ post hoc test if group variances were homogeneous (Levene test statistic)
If the result of the Levene’ test of homogeneity of variances was significant
the Games-Howell post-hoc analysis was performed to locate pairwise differences

Newton North High School presented the Charles Dana Meserve Award
one of the school’s most prestigious honors
is the first Black student to win since the award was created in 1923
The Meserve Award is North’s oldest running award
Students who merit it not only have displayed a high standard of academic excellence
but have also made significant contributions to the community
said his favorite classes were Advanced Placement Chemistry
He is planning to study biochemistry at Yale University in the fall
it leads you to even more questions,” Wright said
I just feel like since I’m very curious about the world and how things work
said the pandemic inspired her to pursue justice in public health
Tarui plans to study biomedical engineering at Johns Hopkins University in the fall
“I was really excited by the opportunities that existed specifically within the [area of] advancing health equity,” Tarui said
“So that was a really big factor in me deciding to attend Johns Hopkins.”
Principal Henry Turner said he is proud of Wright and Tarui’s achievements and commitment to the school community
“They were true leaders in helping the rest of our school community to know what it meant to be a Newton North student,” he said
Turner also said Wright’s achievement was both a recognition of the strides the school has made
as well as a signal of the work still needed to be done
“I think it was pretty eye-opening to many members of our community that we haven’t had a Black recipient for that long of our history,” Turner said
“We’re really proud of our history as a school so I think that provided a lot of shock
“I think it’s a great way to celebrate our community and at the same time a great acknowledgement of the work that we’ve got to do.”
Wright said he learned he was the first Black recipient of the award when Turner told him during a graduation rehearsal
“I was just surprised that in 99 years of the award, I was the first [Black] person to win it,” Wright said. “I think that kind of speaks to something at North, like having an achievement gap between Black students and the rest of the school.”
In the summer going into his senior year, Wright said he participated in Summer Science Program, through which talented high school students gain hands-on research experience, where he helped design inhibitors for diseases. During his junior year he was part of a mentorship program, reading and conducting science projects with younger children in the Newton community.
“It was nice to be the teacher — because I’m used to being in the student’s position — to see how it is to teach other people,” Wright said.
Isongesit Ibokette, who taught Wright in AP United States History, also had him in an elective course called “Africa and the New World.” A presentation Wright gave in that class on the Belgian colonization of the Congo was so outstanding, Ibokette said, he had to postpone the rest of the presentations for the day so that other students could tweak their own projects.
“When I wrote his letter of recommendation I just didn’t know where to stop,” Ibokette said. “Because this is a student that I know Yale University is just going to be very lucky to have on their campus.”
David Bennett, a teacher at North who had Tarui for AP Chemistry and was a faculty adviser for a new student-led, faculty-facilitated group at the school called the Human Rights Council, said he was impressed by Tarui’s level of involvement in the school community.
“It’s hard to imagine where she even had the time,” Bennett said. “She’s truly a wonderful individual. She’s one of those students who you’ll never forget because they’re such good people.”
As part of the Human Rights Council, Tarui worked to address issues of inequality within the school.
Principal Turner said the program came about as a result of several incidents of racism the school dealt with over social media in 2020. One step the administration took at that time was to reach out to students to hear their concerns on the issue.
“One of the things that [students] felt like we needed to do a better job as an administration was to really make sure that students had a voice when those kinds of incidents occur, and to give feedback to administrators like myself,” Turner said. “They wanted more empowerment to be able to create change in their schools.”
This year the group created an initiative to provide SAT Prep tutoring to students who may not have had access to private tutoring.
Tarui, who is the first person in her family to attend a United States university, said her own experience applying to schools inspired her participation in the tutoring program.
“I gained a lot of awareness around the various inequities that exist within higher education and the college application process in general,” she said. “So I became really motivated to want to do something to address those inequities to ensure that students from all backgrounds had access to higher education especially.”
The Meserve Award was announced during a breakfast ceremony held in honor of the graduating class. Wright and Tarui both said, thankfully, they didn’t have to give a speech.
“I had known about the Charles Dana Meserve Award because I had seen the plaque in the hallways,” Tarui said. “But I wasn’t expecting to get it at all, so I was really surprised when they announced my name.”

Bridge adviser Gavin Williams happily reported this year’s efforts had raised more than $10,000
with incoming donations still being tallied
the students said they wanted to do something that brings the whole school together,” said a fuzz-headed Williams
who’d had his own dome chromed at a March 4 assembly introducing the fundraiser
everybody’s been donating in classrooms and talking about it.”

(Raul Roa / Staff Photographer) Williams said this year organizers instituted a “100 to shave/100 to save” structure to allow those too squeamish for a shaving to help the cause by raising enough to keep their hair intact
Among the 20 or more male students and teachers who opted for the former was junior Jake Stolmack
“Hair is a small sacrifice to make to raise awareness about something like cancer,” the 16-year-old reasoned
even the hair on our heads is something we take for granted.”
